GUN CLEANER Filed April 11, 1923 I g.. I ln/ventola L. If. a/'Zzhylamented Een, Si), 193@ LOUIS H. DARLING, F VALLEJO, CALIFORNIA GUNCLEANER Application filed April 11,

The invention provides a device for cleaning the barrels of small gunsand firearms which is effect-ive in operation in removing ruft, lead,carbon and other matter tending to foul the gun, said device beingadjustable and adapted to have the cleaning element readily replaced orinverted, as required, to meet existing conditions.

@ther objects and advantages will be apl@ parent and suggest themselvesas the nature of the invention is understood.

Vilhile the drawings illustrate an embodiment of the invention it is tobe understood that in adapting the same to meet different conditions .ndrequirements, various changes in the form, proportion and minor detailsof construction may be resorted to Without departing from the nature ofthe invention.

Referring to the accompanying drawings 29 forming a part of theapplication:

Figure 1 is a side view of a gun cleaner embodying the invention,

Figure 2 is a central longitudinal section thereof, the stem being infull lines,

Figure 3 is a sectional view on the line 3 3 of Figure 2, looking to theleft, as indicated by the arrows, the blades being omitted.

Figure 4 is a sectional view on the line tt of Figure 2, looking to theright asdesignated by the arrows, the blades being omitted, and

Figure 5 is a detail perspective view of two of the cleaner blades.

Corresponding and like parts are referred to in the followingdescription and designated in the several views of the drawings by likreference characters.

The numeral 1 designates a stem which consists ot a rod having oppositeend portions 13 and 14 screw threaded for a short distance. A collar 2is provided at one end of the stem 1 and is preferably of polygonalform. A retainer 3 cooperates with the collar 2 and is mounted on thethreaded end 13 of the stem. A swab 15 is mounted upon the threaded end13 of the stem 1 and is confined between the retainer 3 and a nut 16.The swab et may be of any suitable material or construction adaptedforthe required work. A slide loose uponv the opposite threaded end of the.item 1 comprises a band 7 and an inner 'TTI 1929. Serial N0. 354,361.

polygonal boss 8. The faces of the boss 8 are lat and receive the flatends 1() of the cleaner elements 11 which are conlined by the band 7; vAstout helical spring 17 is mounted on the stem, between the slide and anut 18 on the threaded end 14 and yieldably holds the said slide pressedinwardly to confine the cleaner elements 11 between the retainer 3 andslide. The spring 17Vis expansible and its tension is regulated by thenut 18.

The cleaner elements 11 consist of narrow blades of spring metal,outwardly bowed between their flat ends 10 and having the latter securedin the manner stated. The cleaner blades 11 are transversely corrugatedas indicated at 12, whereby to provide scraper elements for positivelyremoving the matter adheringto the wall of the gun barrel. The collar 2and retainer 3 occupy a liXed position, whereas the slide is adjustablelongitudinally on the stem 1 whereby to regulate the curvature and bulgeof the cleaner blades. The

' blades have a helical or spiral arrangement to insure contact of thescraping elements 12 with every part of the inner wall of the barrel ofthe gun to thoroughly clean the same.

1n practice, a rod (not shown) may be applied to either threaded end ofthe stem 1 so as to reciprocate the cleaner in the barrel of the gun. Atransverse opening 19 may be provided in an end of the stem 1 to receivea cord or wire (not shown), whereby the clean er maybe drawn through thegun barrel when cleaning the same.

l/hat is claimed is:

1. A gun cleaner comprising a stem, cleaner elements arranged lengthwiseof the stem and grouped about the same, said cleaner elements beingoutwardly curved intermediate their ends, and confining means on thestem engaging opposite ends of the cleaner elements, one of said meansbeing resilient and adjustable to admit of regulating the bulge or' thecleaner elements.

2. A gun cleaner comprising a stem, longif tudinally disposed cleanerelements grouped about the stein and outwardly curved intermediate theirends, conning means on the stem engaging opposite ends or' the cleanerelements, one of said means including an lOfl expansible spring, and aset nut threaded on the stem to adjust the tension of said spring toregulate the bulge of the cleaning elements.

3. A gun cleaner comprising a stern, a collar at one end of the stem, aretainer associated with said collar, a slide loose upon the oppositeend portion of the stem, outwardly bowed cleaner elements confinedbetween said retainer and slide, said cleaner elements beingtransversely corrugated 'from end to end, and a set nut threaded on thestem for regulatin the bulge of the cleaner elements.

4. A gun cleaner comprising a stem having opposite end portions screwthreaded, a retainer at one end ofthe stein, a slide upon the oppositeend of the stein, spring means engaging the slide, outwardly curvedcleaner blades disposed helica'lly about the stem and confined betweensaid retainer and slide and having transverse eorrugations, and a setnut for adjusting' the tension of said means and for regulating thebulge of the cleaner blades.

5. A gun cleaner comprising a stem, longitudinally disposed cleanerelements grouped about the stem and outwardly curved intermediate theirends, conlining means on the stem engaging opposite ends of the cleanerelements, one of said means being loose, a helical spring on the stem,and a set nut threaded on the stem for Varying the tension of saidhelical spring whereby to adjust the loose confining element to regulatethe bulge of the cleaning elements.

6. A gun cleaner comprising a stem7 a collar at one end of the stem, aretainer associated with said collar, a slide loose upon the oppositeend portion of the stem, outwardly bowed cleaner elements confinedbetween said retainer and slide, a helical spring on the stem, and ayset nut threaded on the stem for regulating the tension of said helicalspring and the bulge of the cleaner elements.

7 A. gun cleaner comprising a stem having opposite end portions screwthreaded, a retainer at one end of the stem, a swab on the end of thestem adjacent said retainer, a slide upon the opposite end of the stem,outwardly curved cleaner blades confined between said retainer and slideand having transverse corrugations, a helical spring on the threaded endof the stem adjacent the slide, and a set nut for regulating the tensionof' the spring and the bulge of the cleaner blades.

In testimony whereof I aiiiX my signature.

LOUIS I-I. DARLING.
